I purchased two of the F2 4 Rib 15" BKT font tractor tires ... These Tires are Junk. I had nothing but problems with these tires. Tubeless?? Bull, won't seal on new rims, put tube in them, the construction is not a hard rubber so any abrasions or scuffs are cuts through the tire, Put expensive sealant/ballast in tubes, worked for rest of the season. I haven't had these tire one year and now have a cut in the side wall 4" ... I'm done with BKT

These tires ride nicely and have a great lookbto them.

Good tire for the price.
